Linux N4Supervisor Notes

Niagara 4.2 supports an N4Supervisor running on Red Hat Enterprise Linux 7/CentOS distribution on a specific PC platform (contact your Tridium sales channel for further PC platform details). This document provides installation details specific to this Linux N4Supervisor. For related details on Niagara 4 platform operation, see the Niagara 4 Platform Guide section “Linux-based N4Supervisor.”

 
NOTE: Note that the station running on a Linux N4Supervisor is “owned” by a specially created user/group niagara:niagara, and therefore cannot bind to Linux “root owned” software ports 1-1024. This is not an issue for either of the conventional ports (secure: 5011, or non-secure: 3011) used for a platform connection, but does affect the standard port used by the station’s WebService (Http Port), which cannot be used at the default port (80) setting. In addition, other software ports potentially used by various drivers must be adjusted above port 1024.
